The accelerator, which counts Amazon CTO Werner Vogels among its startup mentors, will be showcasing its first batch of startups (see list below) in Silicon Valley on the 20th of September, followed by a panel discussion about “The Future of the European Startup Community”. Sounds riveting!

In all seriousness, the Q&A panel session will include European entrepreneurs like Guillaume Decugis, who sold Musiwave for $125 million and is currently co-founder and CEO of Scoop.it, and Unity Technologies co-founder and CEO David Helgason (read our interview with him).

These kinds of trips usually yield good returns for participating startups, although it may have been wiser of Rockstart to have started reaching out to the Bay Area tech community and press a little earlier.

Anyway, the Rockstart startups have already been in the States for two weeks now, working out of RocketSpace and networking with VCs, angel investors and other startups in between mentorship sessions at Mozilla, Google, Blackbox, and the Dutch Consulate.

If you’re going to the Demo Day in Silicon Valley, these are the startups you’ll be hearing from:
